Specification of Letters Patent.

Patent-ed Apr. 11, 1911.

Renewed September 3, 1910. Serial No. 580,299.

To all whom it may concern:

Be it known that we, CHARLES W. THOMAS and FRANK B. RILEY, citizens of the United States, residing in Collingswood, New Jersey, and Flemington, lVest Virginia, respectively, have invented certain Improvements in Charging-Tools, of which the following is a specification.

The object of our invention is to improve the construction of a charging tool for which application for patent was filed by Charles W. Thomas .on the 12th day of March 1908, Serial No. 420595, it being es pecially desired to so construct the charging tool that any desired material can be placed upon the furnace floor or hearth in a layer of uniform thickness. It is'also desired that the construction of the tool shall be such as to prevent the rolling up of the material when the bottom slide is withdrawn, as fully described hereafter, reference being had to the accompanying drawings, in which,

Figure 1, is a perspective view of our im proved charging tool. Fig. 2, is a transverse sectional view on the line 22, Fig. 3. Fig. 3, is a longitudinal sectional view on the line 3-3, Fig. 2. Figs. 4 and 5, are diagrammatic views illustrating the manner of operating the tool, and Fig. 6, is a View of a modification.

Our invention applies particularly to a charging tool for introducing granular material into a furnace;the material being packed in the charging tool under condition of use so that said tool may be placed in proper position on the floor of the hearth of the furnace, after which the bottom slide is withdrawn and the tool is raised clear of its charge, which remains intact within the furnace.

The invention is particularly adapted for use in charging or placing within a furnace such materials as silica sand, calcium-carbonate, pulverized glass or analogous materials as well as materials used in the manufacture of artificial stone, poultry grits, calcium oxid, carborundum and the like.

In the above drawings A is a quadrangular metallic frame of any size desired and having a handle C attached in any suitable manner. In the bottom of each side of the frame are channels a and at the top on each side are channels a; there being a bottom plate B fitting the channels aa and a top plate D adapted to fit the channels a. A

said frame is larger at the bottom than at the top and may readily be lifted from the material. In some instances, instead of slid ing the upper plate D in channels a it may be pivoted at d as shown in Fig. 6.

While we have shown the frame as rectangular in shape, it will be understood that it may be of any other desired form, and the construction may be such that either or both of the plates will disengage the channels or guideways when moved a certain distance, so as to rest directly upon the hearth or floor of the furnace.

In operating our charging tool we first close the bottom of the frame with the bottom plate, and then we fill the box so formed with the granular or other material, packing it in if desired, or allow it to fill the frame without being subjected to pressure. The top D is then placed in position so as to close the boX and therefore inclose the material within the frame. The charging tool is then carried to the furnace, and when in proper position on the hearth or floor thereof the bottom plate B is withdrawn so as to allow the material carried to rest directly upon the hearth or floor of the furnace. The top plate is withdrawn and the frame is raised bodily clear of the material, leaving it in shape on the hearth. By the use of a charging tool of this construction the granular material, which has a tendency to adhere to the bottom plate and consequently roll up or ridge when said plate is removed, is held by the top plate so that its upper surface is kept level and the shape of the charge is maintained intact. With some materials it is not necessary to provide a top plate, but in the case of others which adhere more or less to the bottom plate, they must be prevented from rolling up or packing at the inner end of the frame.

By making the charging tool as described it may be easily reversed, as in some instances it may be necessary to place material last put in the frame, directly upon the floor or hearth of the furnace.

It is, of course, possible that if desired the bottom plate B may be permanently fixed to or integral with the frame A, in which case it would be necessary to turn upside down or reverse the charging tool When it was desired to empty the same.

' We claim 1. A charging tool consisting of a frame with movable bottom and top plates.

2. A charging tool consisting of a frame with a bottom plate and a slidable top plate.

3. A charging tool consisting of a frame having a sliding bottom plate and a movable top plate.

4. A charging tool consisting of a frame having sliding bottom and top plates.

5. The combination in a charging tool of a frame having channels at its upper and lower edges, With a bottom plate operative in the channels of the lower edge of the frame, and a top plate operative in the channels of the upper end of the frame.

6. The combination in a charging tool of a frame having channels at its upper and lower edges, a bottom plate operative in the lower channels, a top plate operative in the upper channels, a handle for the frame and rods extending from the top and the bottom plates, with guides on the handle for said rods.

7. The combination in a charging tool of a frame having channels at its upper and lower edges, a bottom plate operative in the lower channels, a top plate operative in the upper channels, a handle for the frame, and rods extending from the top and the bottom plates along said handle.

In testimony whereof, we have signed our names to this specification, in the presence of subscribing witnesses CHARLES W. THOMAS. FRANK B. RILEY.
